Ingredient Notes
Egg noodles are the most classic choice for tuna noodle casserole because they cook quickly and give the dish that familiar soft, comforting texture. Other short pasta shapes can also work, but egg noodles really help give the casserole its traditional feel.
Tuna packed in water is a common choice because it keeps the casserole lighter, but tuna in oil can add more richness if that is what you prefer. Cream of mushroom soup gives the filling its signature creamy texture and savory flavor, while milk loosens it enough to coat the noodles evenly. Peas add a little sweetness and color, and onion gives the casserole more flavor depth.
For the topping, crushed buttery crackers are especially popular because they brown beautifully and bring a rich, crispy finish. Breadcrumbs or fried onions also work well if you want a slightly different texture.
How to Make
1. Preheat the oven
Preheat your oven to 375°F. Lightly grease a baking dish so the casserole is easier to scoop and serve.
This helps the casserole bake evenly and keeps the edges from sticking too much.
2. Cook the noodles
Bring a large pot of salted water to a boil and cook the egg noodles according to the package directions until just tender.
Drain them well and set them aside. Be careful not to overcook them, since they will continue softening a little in the oven.
3. Soften the onion
In a skillet, melt 1 tablespoon of butter over medium heat. Add the chopped onion and cook until softened and lightly translucent.
This small step adds more flavor and helps the onion blend into the casserole better.
4. Make the creamy filling
In a large bowl, stir together the cream of mushroom soup, milk, black pepper, garlic powder, and a little salt if needed.
Then mix in the softened onion, drained tuna, and peas.
The filling should look creamy and well combined, not too thick and not too runny.
5. Add the noodles
Fold the cooked noodles into the creamy tuna mixture until everything is evenly coated.
If you are adding cheese, stir it in now so it melts into the casserole as it bakes.
6. Transfer to the baking dish
Spread the mixture into the prepared baking dish and smooth the top evenly.
Try to distribute the tuna and peas throughout so each serving has a balanced mix.
7. Make the crunchy topping
In a small bowl, combine the crushed crackers, breadcrumbs, or fried onions with the melted butter.
Mix until the topping looks lightly coated and crumbly.
8. Add the topping
Sprinkle the crunchy topping evenly over the casserole.
This layer gives the casserole its signature golden crisp finish and makes a big difference in texture.
9. Bake
Bake uncovered for about 25 to 30 minutes, or until the casserole is hot and bubbling around the edges and the topping is golden brown.
If you want the top extra crisp, you can broil it very briefly at the end, but watch it closely.
10. Rest and serve
Let the casserole rest for about 5 to 10 minutes before serving.
This helps the filling settle slightly and makes the casserole easier to scoop.
Tips for Best Results
Cook the noodles just until tender and not beyond that. Since they bake again in the casserole, overcooked noodles can become too soft by the time the dish is done.
Drain the tuna well before mixing it in. Too much extra liquid can make the filling looser than you want.
If the mixture looks too thick before baking, add a small splash of milk. Different soups vary in thickness, so this helps keep the casserole creamy instead of dry.
Use a topping with butter mixed in if you want the best golden finish. That little step helps the crumbs brown more evenly and gives them better flavor.
Let the casserole rest briefly after baking. It is still creamy and soft straight from the oven, so a few minutes of resting helps the texture come together.
If you want a stronger savory flavor, add a little cheese to the filling. Cheddar or Parmesan both work well without taking away from the classic feel.

Storage and Reheating
- Refrigerator: Store in an airtight container for up to 4 days
- Freezer: Freeze for up to 2 months
- Reheating: Warm in the oven or microwave until heated through
- Best tip: If reheating in the oven, cover loosely with foil at first so the top does not brown too fast
If the casserole seems a little dry after refrigeration, add a tiny splash of milk before reheating.
Common Mistakes to Avoid
One common mistake is overcooking the noodles before baking. That can make the casserole too soft instead of creamy and satisfying.
Another is not draining the tuna well enough, which can make the filling watery.
Using too little milk can also leave the casserole dry, especially if your canned soup is extra thick. It is always fine to add a bit more if needed.
Finally, do not skip the topping. The crunchy top is one of the best parts of the whole dish and gives the casserole the texture contrast that makes it feel complete.
